Subject: message header parser: Allow NULs in header name also when header is missing ':'.
X-Git-Tag: 2.0.14~71
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4bd6702bfcb3568959acdb3cb68450aa76ed703b;p=thirdparty%2Fdovecot%2Fcore.git

message header parser: Allow NULs in header name also when header is missing ':'.
This doesn't fix any crashes/corruption unlike the earlier fix, but it makes
the code more correct. Although it might help with mbox rewriting seeing
some size mismatches (or might not).
